 In this project, you'll build a robot liar that uses MIDI-controlled servo motors to pluck its strings. The robot uses the PCA9685 to drive the servo motors. It's connected over I2C to a feather RP2040 running circuit Python. The circuit Python code listens for incoming MIDI messages over USB. If a note is played that matches the array, then the corresponding servo is moved. The build rests on a piece of acrylic paired with 3D printed parts. These include a cage that places the servos directly above each string, and horn extenders to pluck the strings. You can control the robot liar with a MIDI controller via USB MIDI host, or through a DAW by configuring the robot as a MIDI output.
